Overview
The LM293ADGKRG4 is a dual differential voltage comparator manufactured by Texas Instruments, belonging to the LM293A series. It features an SOIC-8 surface-mount package and operates on a single power supply ranging from 2 V to 30 V. The device provides a typical response time of 1.3 µs and draws 1 mA of operating supply current. Key electrical specifications include a maximum input offset voltage of 2 mV and an input bias current of 250 nA. It supports CMOS and TTL output compatibility and functions within a commercial temperature range of -25 °C to +85 °C.
Feature Summary
- Dual differential input configuration for precise signal comparison
- Open-collector outputs compatible with CMOS and TTL logic families
- Wide single-supply voltage operation capability
- Low input offset voltage for improved accuracy
Applications
- Overvoltage detection circuits
- Window comparator designs
- Level shifting applications
- Temperature sensing interfaces
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications, as availability may be limited. Ensure the specific suffix matches required packaging and quality standards for your manufacturing process.
Selection Notes
Select this component when dual comparators are needed in a compact SOIC-8 package. It is suitable for applications requiring low input offset voltage and wide supply voltage ranges. Consider thermal performance and output drive requirements relative to the load connected to the open-collector pins.
Part Context
This part is part of the LMx93/LM2903 family of dual differential voltage comparers designed for single-supply operation. These devices are engineered for cost-effective solutions in consumer electronics and industrial control systems where space constraints and power efficiency are critical design factors.
Replacement Considerations
LM293DRG4: Pin-compatible alternative with similar electrical characteristics but potentially different temperature range or speed specifications.
